Hordhac u kala soocidda lebenka refractory alumina sare marka loo eego nuxurka Al2O3

Lebenka aluminiumka ah ee sare u kaca ayaa loo qaybiyaa saddex darajo iyadoo loo eegayo nuxurka Al2O3: Fasalka I (Al2O3> 75%); Fasalka II (Al2O3 waa 60% ~ 75%); Fasalka III (Al2O3 waa 48% ~ 60%). Marka loo eego halabuurka macdanta, waxaa loo qaybin karaa: mullite hoose (oo ay ku jiraan sillimanite) iyo mullite (Al2O3 waa 48% ~ 71.8%), mullite-corundum iyo corundum-mullite (Al2O3 waa 71.8% ~ 95%), corundum (Al2O3). waa 95% ~ 100%) iyo lebennada kale ee diidmada ah.
